3 is plenty. One is enough but don't even try to remember more than three. You put one to three learning objectives on your refrigerator and focus on helping your child learn
- three new words
- three new ways to use words
- how to play with three new toys
- how to play with three new people
- Or any combination of new ideas or skills--3 is enough.
If your child does not seem interested in the skills you have chosen, choose something different.
